Default cant connect to exchange server

Windows 2000 SP4 Outlook 2003

Cant connect to Exchange server

I have a box that is not part of my employer's domain. When I fired
up Outlook this week it has stopped being able to connect to the
exchange server. It used to prompt me for authentication
(username/password) but now it doesn't. The last email in Outlook on
this system was Jan 4.

When I tried blowing away my profile and set up a new one I get an
immediate response about Outlook not being able to connect to the
server.

Someone told me that they remember something like this where Outlook
is sending the authentication info when it shouldn't and there was
some way to "reset" Outlook not to send the authentication info.
Again, I've checked the "always prompt for pasword" in Outlook but it
never does.

Found the solution after many hours searching:

quote:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\ClientPr otocols


In all cases where this problem was occuring, I verified and found
that either 1) the key was missing or 2) it was incorrect.


The correct entries are as follows for ClientProtocols:
ncacn_http REG_SZ rpcrt4.dll
ncacn_ip_tcp REG_SZ rpcrt4.dll
ncacn_nb_tcp REG_SZ rpcrt4.dll
ncacn_np REG_SZ rpcrt4.dll
ncacn_ip_udp REG_SZ rpcrt4.dll


You might also want to verify and tweak (not as touchy as it was under
Windows Messaging and all that nonsense years ago) the values and
order of the rpc bindings under:


HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Exc hangeProvider\Rpc_BindingĀ*_Order


Rpc_Binding_Order REG_SZ
ncalrpc,ncacn_ip_tcp,ncacn_spx,ncacn_np,netbios,nc acn_vns_spp
